我厂和济南铸造锻压机械研究所的广大职工,高举“鞍钢宪法”的伟大红旗,以阶级斗争为纲,开门办科研,大搞三结合,密切合作,设计和试制成功了一套锥阀式液压集成系统。它的外貌见图1。基本零件很简单,仅由阀套阀芯和弹簧三个零件组成一套锥阀,如图2。 I plant and Jinan forging Machinery Research Institute of the general staff, hold high the “Great Red Flag of Ansteel Constitution”, with class struggle as the key link, open the door to do research, engage in three combinations, close cooperation, the design and trial success of a cone valve Hydraulic integrated system. Its appearance is shown in Figure 1. The basic part is very simple, only by the valve sleeve and spring three parts to form a set of cone valve, shown in Figure 2.
